Have you experienced problems with accessing network card on P550 when running firmware release 2024.11.00-HFP550? We observed such issues compared to version 2024.09.00-HFP550 , which works fine. Not sure if that is related to the way how we built 2024.11.00-HFP550 using Yocto, or is it specific to the board we have, or there is some software/configuration issue with 2024.11.00. Unfortunately, we did not have possibility to dig it further.
Hi @gdhh,
If you are using any external network card then could you provide more details about the network card you’re using?
If you have issue with inbuilt ethernet adaptor then can you please check the MAC of the ethernet adaptor using below command.
ip link show <interface>
Replace <interface> with the adapter’s name (e.g., eth0 or enp0s3). The MAC address is listed as link/ether followed by the address.
If the MAC address appears as 0 or is blank, please let us know.
RahulMoorkoth. We are only using the internal (inbuilt) ethernet adaptor. The MAC address is valid, not blank or zero. checked via the MCU console, not with a linux command. We went to a functional (different) release so we could continue our work. If there is some test you would like us to run, let us know. If you would like us to do some testing on a failing release let us know. Thanks.
We may have a related issue.
On our Premier P550 board, with the most recent preinstalled Ubuntu 24, we are seeing duplicated and invalid MAC addresses “8c:00:00:00:00:00” on the built-in Ethernet interfaces end0 and end1. In comparison, the Apple USB Ethernet adapter enx804971111a8a has a valid MAC address.
$ ip link

Is there some way to reset our end0 and end1 to use unique and valid MAC addresses?
Thanks,

@mmunm AFAIK, the MAC addresses are set at u-boot phase. u-boot reads the AT24 EEPROM and get the MAC addresses at offset 0x72 and 0x78. These addresses then got assigned ethaddr and eth1addr. Later, before hand off to grub or linux kernel, these address will be embedded into the device-tree, as the local-mac-address property of the 2 ethernet gmac. You may want to first check those variables during u-boot phase.
@mmunm Some boards have an incorrectly written MAC address in the EEPROM. We plan to release a software utility to write the correct MAC address. In the meantime, you can set a random MAC address using the microcontroller’s CLI, as described on page 16 of premier-p550-mcu-user-manual
@mmunm, you can use the instructions that @RahulMoorkoth as pointed to and program MAC-IDs that are printed on the stickers on the board. If this board was purchased recently then it might have an issue with the MAC-IDs programmed in it and we will formally provide instructions in a few days.
@Raza @RahulMoorkoth @ganboing : thank you all for your replies. I will hold on for the software utility to come out, and meanwhile use a PCIe network adapter.
